Hi guys, i´m new to Power Bi. I have this problem, i need to substract 9/20/2021 8: 30 AM Kwh del value less 9/20/2021 6AM Kwh del value. I tried creating a new table by hour (8:30 am and 6 AM) and then subtractring both tables but it didn´t work. Any idea of how to accomplish this ??

Date and time can be easily manage by Power Query. try it .

 

if you still have a problem share your excel and PBI file

I know I could use substract option in Power Query but since I have to substract two values from the same column and the same date it's not easily solved by Power Query.  My excel an PBI is in the following link link https://drive.google.com/drive/folders/14anYZ-pPtnwpNCovrHIFthlQgVJiSgr3?usp=sharing
